You could argue that it would be worth the approximate cost of shipping to get it there. Roughly to ship something like that from here to the states would be $800 if you have an known shipper and were to air freight from the midwest.

So find a similar engine in the US that is in similar condition add $800 US and you should be in the ball park. That's a good rule of thumb. I sell my equipment worldwide for the same price as stateside. I can ship engines overseas for slightly more than domestic.

It's surprising that I can send a boat to Ireland for 2,000 (20' ocean freight container) and for me to have a boat trucked from Minnesota to Florida its 1400.
